A comparison would be to a clustered file system, however, unlike other clustered file systems, CSV does not use any proprietary technology — it uses standard NTFS, so there is nothing special you need to purchase or support — it just works!
If your storage is suitable as a standard clustered disk, it can be used as a Cluster Shared Volume. In the past, only one node could host a virtual machine VM and access the VHD on the shared storage, so if another node needed to host the VM or access the disk, it would need to failover and it would affect every resource on that shared disk. With CSV in R2, any node can host the VM and any node can access the VHD on shared storage, so VM and disk ownership can move freely across cluster nodes without impacting any other resources on that shared disk.
CSV will provide many benefits, including easier storage management, greater resiliency to failures, the ability to store many VMs on a single LUN and have them fail over individually, and most notably, CSV provides the infrastructure to support and enhance live migration of Hyper-V virtual machines. We will discuss other benefits and features of CSV and live migration in future posts. All information is based on the Beta build of Windows Server R2 and is subject to change for the RTM version of this product.
To configure CSV we must first build the cluster. It probably is something related to cloning that a sysprep is not addressing and as you say, you can always just do fresh installs, it's just that the space you can save using differencing disk is really enticing especially when you want to store multiple labs on a laptop SSD drive. Hi onooka, this is your third posting of this issue. Please try not to multi-post since it causes us answerers and moderators extra unnecessary work.
Your issue has been answered here and here. I have installed the SQL Successful!!!!! I see the problem was the VirtualBox in Guest Additions. Any luck with thi please tel me what to do. I successfully configured clustering windows server R2 Enterprise Edition and sqlserver in cloud services with resolving below error's, very simple changes.
Step 1 : we should use private IP's for internal share disks iscsi configuration. Step 2 : when we are configuring DNS we don't won't create reverse look up zone and forward lookup zone just we need to create DNS only. Step 3: just we are providing DNS ip in client machines , adding domain in client machines. Reboot 3. Open Device Manager, Scan for hardware changes 5. Once the Windows drivers are installed for the virtual network adapter you can re-add your static IP info ".

I'm getting stuck at the Instance Configuration screen, i get an error when trying to detect the SQL Server Network Name, here is the error: The given network name is unusable because there was a failure trying to determine if the network name is valid for use by the clustered SQL instance due to the following error: 'The network address is invalid.

Technically yes. Exchange CCR clusters do not have shared storage but likely that is not your goal. Already provided this answer, use free iSCSI target and test with virtual machines. Santosh has already provided the links. Yes of course! As a result you'll end with only TWO machines and everything will run fully redundant.
Hope this helped :. Take a look at this one:. Something being unacceptabe for production. Iam fully cnfdnt about the AD and additional AD ,dns and dhcp.
The problem is with the failover clustering. Though a domain controller isn't cluster aware however, you can have cluster nodes as domain controllers. In fact, such situations are very rare to find! Windows , Windows Server , and Windows Server cluster nodes as domain controllers. Office Office Exchange Server. Not an IT pro? Windows Server TechCenter. Nodes Each node in the cluster is represented in the console tree underneath the Nodes option Figure B.
When you select a node, all of the details for that node appear in the work pane in the middle of the screen. If you want to add a disk to the cluster, right-click this option and, from the shortcut menu, choose Add Node.
Figure B Details of one node in this cluster. Storage Selecting the Storage option in the navigation pane shows you, in the work pane, a list of all of the disks shared in the cluster Figure C. If you want to add a disk to the cluster, right-click this option and, from the shortcut menu, choose Add A Disk. Figure C A list of the storage resources present in the cluster. Networks Each network in the cluster is represented in the console tree in the Networks option Figure D.
When you select a network, all of the details for that network appear in the work pane in the middle of the screen. Figure D Details of one network in the cluster. You can indicate whether the cluster should use a particular network by right-clicking an individual network entry and, from the shortcut menu, choosing Properties. Figure E Change the configuration of a network. Cluster Events This link houses all of the events related to the cluster service.
Working with the tool's wizards The Failover Cluster Management tool provides wizards that help you accomplish common tasks such as setting up a cluster, adding nodes, adding groups, and adding resources. Validating your hardware configuration Before you create a cluster, you should examine your infrastructure to make sure it's ready to support your new high-availability configuration. In the Actions pane, choose Validate A Configuration.
The first screen of the wizard is simply informational. Click the Next button to continue. Figure F Figure F Enter the names of the servers that will take part in the cluster. A couple dozen tests are run that validate your configuration, including enumerating your iSCSI or Fibre Channel host adapters, clustered network configuration, cluster member firewall exception configuration, and storage files system. You can run all of the tests if you like, or you can choose which tests to run Figure G.
If you opt to run all of the tests, the process can take a bit of time. Figure G Decide which tests you want to run. After you make your selections, they will be listed for you to review. Once you confirm your choices, click the Next button to begin the analysis Figure H.
Figure H Confirm your choices. Creating a cluster The goal of your management efforts is to cluster your servers. In the Actions pane, choose Create A Cluster. Select Servers Choose the servers that will comprise the cluster. Use the Browse button to browse Active Directory for servers. Figure I Figure I Provide the names of the servers that will take part in the cluster.
